Heat 2 tablespoons of extra virgin olive oil in a pan over medium heat. Remove the chorizo from the casings and add to the pan and cook, breaking the sausage into smaller bits as you go, until nicely browned about 8-10 minutes

Peel and chop the onion, add to the pan and toss to coat in the oil from the sausage. Sprinkle with 1/2 teaspoon each of kosher salt and ground black pepper. Cook for 6-8 minutes or until the onions are very tender. Add the sausage back in and remove from the heat

Preheat your oven to 450 F. Place the flatbread on a sheet pan. Scoop the chorizo and onion mixture onto the flatbread. Top with some shredded mozzarella cheese. Place in the oven and cook for 20 minutes or so keeping an eye on it. Your really looking for a nice golden brown and bubbly cheese here. You can even use broil for the last few seconds but be sure to pay attention as they can cook to fast

Let the pizza rest a few minutes. Crumble some queso fresco cheese, chop up some fresh cilantro and sprinkle them over the chorizza and serve
